前提条件： 完成 Oracle GoldenGate 12.3.0.1.4 in Oracle 12.2 之03(预安装) 中的步骤1到9 配置
1.管理服务器资源(xag130,xag131)
#默认情况下，一个集成的捕获摘录请求日志挖掘服务器以MAX_SGA_SIZE1GB 的速度运行。
#因此，如果在同一数据库实例中以集成捕获模式运行三个提取，则需要至少3 GB的内存分配给Streams池。
#最佳做法是保持25％的流池可用。例如，如果在集成捕获模式下有3个摘录，请将STREAMS_POOL_SIZE数据库设置为以下值：
# 3 GB * 1.25 = 3.75 GB
--SQL> alter system set streams_pool_size=3.75 GB
#本次测试用2个提取，每个 MAX_SGA_SIZE= 200M 来测试故 即 TRANLOGOPTIONS INTEGRATEDPARAMS (max_sga_size 200, parallelism 2)
[oracle@xag130 ~]$ sqlplus / as sysdba
SQL> alter system set streams_pool_size=500M scope=both;
SQL> show parameter streams_pool_size;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
streams_pool_size big integer 500
2.源端配置Extract进程参数（xag130）
[oracle@xag130 ~]$ cd $OGG_HOME
[oracle@xag130 ogg]$ ggsci
GGSCI (xag130) > DBLOGIN USERID c##ogg_admin, PASSWORD 123456

3.注册 extract

4.创建integrated replicat RT002

5.初始数据导入
[oracle@xag130 ~]$ sql xag/123456@xag130:1521/pdb1
SQL>SET SQLFORMAT ansiconsole
SQL> select current_scn from v$database;

#导入dmp文件中的所有数据，例：
[oracle@xag131 ~]$ impdp xag/123456@xag131:1521/pdb1 directory=mydir dumpfile=xag2.dmp logfile=xag2.log full=yes
6.Start the Manager, Extract, and Replicat, and Test the Result
